> If a 401 challenge is received this could be handled explicitly in HTTPConduit.handleResponse() (instead of relying on the JVM-wide java.net.Authenticator instance).
> The logic should include the following steps:
> 1. check if the last request payload was cached, on the basis of the content of type OutputStream.class set on the corresponding outMessage
> 2. if only a standard WrappedOutputStream is set as the message content, then a transparent resend is not possible and an exception should be thrown up to the application
> 3. if on the other hand, a fully caching output stream is there, then the last payload is available for resend, which may be acheived as follows:
> 3a. increment the number of transparent resends we've done for this targetURI
> 3b. get the HttpURLConnection from the previous outMessage via the HTTP_CONNECTION property
> 3c. if the threshold for the number of transparent resends has beend reached, then turn back on chunking on the HttpURLConnection, unless config has explicitly turned this off permanently
> 3d. call HTTP.send() again on the old outMessage to set the content to a fresh output stream
> 3e. copy the cached request payload onto the new output stream and flush() & close() the stream
